FFC, FPC (Flat Flexible) Connectors - Housings

Flat Flexible Connectors (FFC) and Flexible Printed Connectors (FPC) are two different types of electrical connectors that accommodate the need for different applications. The term “FFC” generally applies to modular connectors whereby either the male or female part of the connector consists of a flat flex design. FPC is more of an all-in-one plug-in form factor, where both the male and female part of the connector are printed on a single flexible part.

The 485893-6 is an example of a FFC housing. It is a 6-way surface mount right angle FFC/FPC housing specifically designed for use with flat flexible cables. These housings feature cavities that are 2.3mm wide and accept individual flexible connectors with a maximum cable size of 0.5mm. It also has integral strain relief for easy installation, self-positioning pegs for mounting and a large retention force for secure mating.

FFC/FPC connectors provide a cost effective means of connecting FFC/FPC cables to printed circuit boards in a variety of applications. These applications include a variety of sectors such as consumer electronics, automotive, industrial, communications and home appliances. FFC/FPC connectors are becoming increasingly popular for mobile devices, particularly in cellular phones, digital cameras, MP3 players and tablet PCs, due to their small size and comfortable grip. In addition, these connectors provide advantages such as improved resistance to dust, water and EMI, while also being relatively cheap, durable, and abrasion resistant.

The principle of operation of FFC/FPC connectors is fairly straightforward. The male FFC cable insert is inserted into the FFC connector, aided by the self-positioning pegs. The contact blades then fit into the crimped contacts on the assembly side. The assembly pins then fit within the slots on the other side, causing the two parts of the connector to mate. The contact blades will come in contact with the printed circuit board as the assembly pins go in, thus establishing the electrical connection. The contact blades are then pressed down against the board, thus ensuring a good connection between the cable and the board.

In conclusion, the 485893-6 is a 6-way FFC/FPC housing that is designed for a variety of applications, including mobile devices, automotive, industrial, communications and home appliances. It features a number of advantages, such as improved dust, water and EMI resistance, small size, comfortable grip, cost effectiveness, and good electrical connections. Its working principle is also relatively simple, involving the insertion of the male FFC cable insert into the FFC connector, followed by the contact blades being pressed down against the printed circuit board.
